Waqtigan xaadirka ah, inta badan tignoolajiyada soo bandhigida crystal dareeraha ah waxay ku saleysan yihiin seddexda tignoolajiyada ee TN, STN, iyo TFT.Sidaa darteed, waxaan ka wada hadli doonaa mabaadi'dooda hawlgalinta saddexdan tignoolajiyada.Nooca TN ee tikniyoolajiyadda soo-bandhigidda dareeraha dareeraha ah ayaa la odhan karaa waa tan ugu aasaasiga ah ee bandhigyada crystal dareeraha ah, iyo noocyada kale ee bandhigyada crystal dareeraha ah ayaa sidoo kale la odhan karaa in lagu hagaajiyo nooca TN asal ahaan.Sidoo kale, mabda'a hawlgalka ayaa ka fudud tignoolajiyada kale.Fadlan hoos ka eeg sawiradaWaxaa lagu muujiyey jaantusku waa jaantus qaab-dhismeedka fudud ee muraayadda dareeraha ah ee TN, oo ay ku jiraan polarizers ee jihooyinka toosan iyo kuwa toosan, filim toosan oo leh jeexdin wanaagsan, walxo crystal dareere ah, iyo substrate dhalo ah.Mabda'a horumarinta ayaa ah in walxaha dareeraha ah ee dareeraha ah lagu dhejiyo inta u dhaxaysa laba muraayado hufan oo hufan oo leh polarizer toosan oo ku xiran dhidibka indhaha, iyo molecules crystal dareeraha ayaa si isdaba-joog ah loo rogaa iyadoo loo eegayo jihada jeexjeexyada ganaaxa ee filimka toosan.Haddii goobta korontada aan la samayn, iftiinku wuu siman yahay.Waxa ay ka soo gashaa saxanka dabaysha, waxa ay u rogtaa jihada ay u socoto iyada oo la raacayo molecules-ka dareeraha ah, ka dibna ka soo baxa dhinaca kale.Haddii laba xabbo oo galaas ah ay tamar helaan, waxa abuurmi doona garoon koronto oo u dhexeeya labada qaybood ee muraayadda, taas oo saamayn doonta isku-xidhka dareeraha molecules-ka dareeraha ah ee dhexdooda, taas oo keeni doonta in ulaha molecular ay qalloocaan, iftiinkuna ma noqon doono. awood u leh inuu dhex galo, taas oo xannibaysa isha iftiinka.Ifafaalaha is-barbardhigga iftiinka-madow ee habkan lagu helay waxaa loo yaqaannaa saamayn beereedka qalloocan, ama TNFE (waxyeellada beerta nematic qalloocan) ee gaaban.Bandhigyada crystal dareeraha ah ee loo isticmaalo alaabada elektiroonigga ah waxay ku dhawaad dhammaan ka samaysan yihiin bandhigyo crystal dareere ah iyadoo la adeegsanayo mabda'a saamaynta beerta nematic qalloocan.Mabda'a soo bandhigida nooca STN waa la mid.Farqiga u dhexeeya ayaa ah in molecules-ka dareeraha ah ee TN-maroojinka nematic field-ka uu ku beddelo iftiinka dhacdada 90 darajo, halka saamaynta STN super-nematic field saamaynta ay ku beddesho iftiinka dhacdada 180 ilaa 270 darajo.Waa in lagu sharxaa halkan in muraayadda dareeraha ah ee TN ee fudud lafteeda ay leedahay laba xaaladood oo iftiin iyo mugdi ah (ama madow iyo caddaan), mana jirto hab lagu beddelo midabka.Bandhigyada dareeraha ah ee STN waxay ku lug leeyihiin xiriirka ka dhexeeya walxaha crystal-ka dareeraha ah iyo ifafaalaha faragelinta iftiinka, markaa midabka muuqaalku waa cagaar khafiif ah iyo oranji.Si kastaba ha noqotee, haddii shaandhada midabka lagu daro monochrome STN LCD ee caadiga ah, iyo pixel kasta (pixel) ee muraayadda muraayadda monochrome waxaa loo qaybiyaa saddex-pixels, filtarrada midabka ayaa la dhex maraa Filimku wuxuu soo bandhigayaa saddexda midab ee aasaasiga ah. casaan, cagaar, iyo buluug, ka dibna midabka qaabka midabka buuxa ayaa sidoo kale lagu soo bandhigi karaa iyada oo la hagaajinayo saamiga saddexda midab ee aasaasiga ah.Intaa waxaa dheer, xajmiga shaashadda ee TN-nooca LCD, ayaa hoos u dhigaya isbarbardhigga shaashadda, laakiin tiknoolajiyada la hagaajiyay ee STN, waxay ka dhigi kartaa la'aanta isbarbardhigga.
